wooo, how long have you got? First off, the Engineers arent part of the system, theyre invaders. The black gloop is some kind of transmugenic agent, a bio weapon, which changes life forms. The worms are native to LV427 or whatever the planets called and after being exposed to the goo, rapidly mutate into hammerheads. The goo presumably makes any living thing able to further mutate, so when it is introduced into the human body, either by the mouth or via ingestion in the wine,it uses the genetic material to procreate. after intercourse with his partner, the girl becomes pregnant with whats referred to as the Trilobite. This later attacks an engineer and produces a further life form called the Deacon, which burst out at the end. For me, this is the films failing,theres no cohesion between the process,or connection between the host body and the mutation. Looks like the next film, Paradise will deviate even further too!

as in the previous alien films, the Alien itself takes genetic material from the host and uses that to create a new creature capable of survival in extremis and being a killing machine. The basic form is adapted dependant on the host, so we have the original Kane alien resulting from human stock, the more spidery insectoid Aliens in Camerons film, born from the queen - which may be closer to the original being and the dog alien from Alien 3, which emerges from the Rottweiler. Things get really messed up with Alien 4, with the third generation Newborn, the product of natural gestation in Ripley.

earth was largely abandoned after the initial contact, but when the awakened engineer realised that the earth mutations had achieved space travel, he was going to return and wipe the slate clean. presumably the vases were stored bio weapons, ready to use as a threat, deterrent, bargaining chip or the means to wipe out every other sentient species, giving the Engineers the run of the system
